What is the Python version?

I'm struggling with an "Early Exit" error for quite some time now. My code is 100% unit-tested, and of course all the test maps work with the local engine. After lots and lots of frustration, I decided to check against Python 2.5, and here's the cache: tuples don't have an 'index' method in python2.5; And I use tuples quite heavily, since they can be iterated almost twice as fast as strings; immutability also gives a slight speedup, too.

So, it would be very nice to have multiple versions of Python, or at least a recent one. I'll try using #!/usr/bin/env python2.6, see if it works. Has anyone more information about Python versions?

Yes, Python is version 2.5, as mentioned in the .Unfortunately we are not able to upgrade the software, to do this is would require a lot of work and we haven't heard any good arguments for needing a newer version.

I just found out this post and reviewed the FAQs, and for what it is worth, I believe limiting to Python 2.5 really sucks!

All the other languages are using latest available releases (such as Ruby 1.9!!!, but Python is stuck to 2.5 (which is not the latest current release since Oct 2008!!!)

Python 2.6 offers some speed improvements over 2.5 (between 5-15%) and:* supports epoll under linux, which allows async style programming with great performance!* supports some functional programming patterns (e.g. filter/map/reduce) with much better performance than 2.5* and I am sure I am forgetting dozen of other things (http://docs.python.org/whatsnew/2.6.html)

If you guys are saying that upgrading to 2.6 is a lot of work, because you are using a linux distro who uses Python 2.5 for many os level tools (such as RedHat/CentOS), let me know. I have built successfully my own Python2.6 rpms for such distros, and would be happy to share
